A New Type of Tree Climbing Device and Its Theoretical Analysis

In view of such issues as high labor intensity,low efficiency and high risk factors involved in high-altitude operations in such forestry fields as pine cone picking in forest areas in North China,a tree climbing device with no additional power source device is designed,which can not only guarantee the safety during high-altitude operation but also improve operation efficiency.The design model of this device is introduced in brief,with focus placed on the theoretical analysis of the mechanism and force of the tree climbing device.
